Written by Augur from the 83 reviews analyzed

This peptide booster serum comes in a lightweight, fluid hybrid formula, ideal for daily hydration and plumping of the skin. Users particularly appreciate its water-like texture that absorbs instantly without leaving a greasy film, as well as its gentleness on sensitive or reactive skin thanks to the absence of fragrance and irritating active ingredients.

This confuses me but it’s nice. I thought it was a facial Mist but it’s not. It has a squirt top which I love but it’s thicker like a like a phyto-mucin so it fits into the serum part of your routine. I like that it’s scent free for the most part and love how it helps my skin. I give it a 4 and not a 5 mostly bc I didn’t and still don’t entirely understand the product.

Sensitive skin friendly, lightweight, hydrate your skin, fragrance free, good absorption,makes skin softer. Its non comedogenic. But Does give you glass skin but good for skin.

Desde que mi madre lo probó, no se lo puede quitar de la ducha. Le fascina lo ligero que es, lo rápido que se absorbe, y cómo su piel queda suave, luminosa y con un “efecto jugoso”.Lo mejor: ese cóctel de 6 péptidos + niacinamida + ácido hialurónico que parece realmente actuar, dando firmeza e hidratación sin sensación pesada.Perfecto para mimarte día tras día.
